A browser is still a tool, so it makes sense that you’ll want to pick the best one for the job. If you’re a human who needs to work to survive, you’ll need a fast internet browser. One thing to keep in mind is a browser that runs third-party trackers is more likely to be slower than a browser that doesn’t. Third-party trackers are cookies, and while you can’t see them, they are running in the background of the site, taking up precious time. The more third-party trackers a browser blocks, the faster it can run.

{ -brand-name-firefox } is offering something new to keep you safe: <a { $monitor }>{ -brand-name-mozilla-monitor }</a>. It’s a free service that will alert you if there are any public hacks on your accounts and let you know if your accounts got hacked in the past. Another neat feature is the Green Lock. It looks like a small green icon at the top left side of the browser window. If you’re on { -brand-name-firefox } and see the green lock, it means the website is encrypted and secure. If the lock is grey, you might want to think twice about entering any sensitive information.

Privacy on the web is a hot button issue. If privacy is number one on your list of priorities, you want to look for a browser that takes that seriously. When choosing the best private browser for you, look at the tracking policy and how a browser handles your data. These seem like technical questions, but they’re the reason some browsers are more private than others.

A web browser takes you anywhere on the internet, letting you see text, images and video from anywhere in the world.

A web browser takes you anywhere on the internet. It retrieves information from other parts of the web and displays it on your desktop or mobile device. The information is transferred using the Hypertext Transfer Protocol, which defines how text, images and video are transmitted on the web. This information needs to be shared and displayed in a consistent format so that people using any browser, anywhere in the world can see the information.

Websites save information about you in files called <a href="{ $cookies }">cookies</a>. They are saved on your computer for the next time you visit that site. Upon your return, the website code will read that file to see that it’s you. For example, when you go to a website, the page remembers your username and password – that’s made possible by a cookie.

When the web browser fetches data from an internet connected server, it uses a piece of software called a rendering engine to translate that data into text and images. This data is written in <a href="{ $html }">Hypertext Markup Language</a> (HTML) and web browsers read this code to create what we see, hear and experience on the internet.
